<p>The eofbit is set by the following standard library functions:
</p>
<ul>
<li> The string input function <span class="t-lc"><a href="../../string/basic_string/getline.html" title="cpp/string/basic string/getline">std::getline</a></span> if it completes by reaching the end of the stream, as opposed to reaching the specified terminating character.
</li>
<li> The numeric input overloads of <a href="../basic_istream/operator_gtgt.html" title="cpp/io/basic istream/operator gtgt"><tt>basic_istream::operator&gt;&gt;</tt></a> if the end of the stream was encountered while reading the next character, on Stage 2 of <a href="../../locale/num_get/get.html" title="cpp/locale/num get/get"><tt>num_get::get</tt></a> processing. Depending on the parsing state, <code>failbit</code> may or may not be set at the same time: for example, <span class="t-c"><span class="mw-geshi cpp source-cpp"><span class="kw4">int</span> n<span class="sy4">;</span> istringstream buf<span class="br0">(</span><span class="st0">"1"</span><span class="br0">)</span><span class="sy4">;</span> buf <span class="sy1">&gt;&gt;</span> n<span class="sy4">;</span></span></span> sets <code>eofbit</code>, but not <code>failbit</code>: the integer <span class="t-c"><span class="mw-geshi cpp source-cpp"><span class="nu0">1</span></span></span> was successfully parsed and stored in <code>n</code>. On the other hand, <span class="t-c"><span class="mw-geshi cpp source-cpp"><span class="kw4">bool</span> b<span class="sy4">;</span> istringstream buf<span class="br0">(</span><span class="st0">"tr"</span><span class="br0">)</span><span class="sy4">;</span> buf <span class="sy1">&gt;&gt;</span> boolalpha <span class="sy1">&gt;&gt;</span> b<span class="sy4">;</span></span></span> sets both <code>eofbit</code> and <code>failbit</code>: there was not enough characters to complete the parsing of the boolean <span class="t-c"><span class="mw-geshi cpp source-cpp"><span class="kw2">true</span></span></span>.
</li>
<li> The character extraction overloads of <a href="../basic_istream/operator_gtgt2.html" title="cpp/io/basic istream/operator gtgt2"><tt>operator&gt;&gt;<span class="t-dsc-small">std::basic_istream</span></tt></a>, if the end of the stream is reached before the limit (if any) on the number of characters to be extracted.
</li>
<li> The <span class="t-lc"><a href="../manip/get_time.html" title="cpp/io/manip/get time">std::get_time</a></span> I/O manipulator and any of the <span class="t-lc"><a href="../../locale/time_get.html" title="cpp/locale/time get">std::time_get</a></span> parsing functions: <a href="../../locale/time_get/get.html" title="cpp/locale/time get/get"><tt>time_get::get</tt></a>, <a href="../../locale/time_get/get_time.html" title="cpp/locale/time get/get time"><tt>time_get::get_time</tt></a>, <a href="../../locale/time_get/get_date.html" title="cpp/locale/time get/get date"><tt>time_get::get_date</tt></a>, etc., if the end of the stream is reached before the last character needed to parse the expected date/time value was processed.
</li>
<li> The <span class="t-lc"><a href="../manip/get_money.html" title="cpp/io/manip/get money">std::get_money</a></span> I/O manipulator and <a href="../../locale/money_get/get.html" title="cpp/locale/money get/get"><tt>money_get::get</tt></a> function, if the end of the stream is reached before the last character needed to parse the expected monetary value was processed.
</li>
<li> The <a href="../basic_istream/sentry.html" title="cpp/io/basic istream/sentry"><tt>basic_istream::sentry</tt></a> constructor, executed at the beginning of every formatted input function: unless the <code>skipws</code> bit is unset (e.g. by issuing <span class="t-lc"><a href="../manip/skipws.html" title="cpp/io/manip/skipws">std::noskipws</a></span>), sentry reads and discards the leading whitespace characters. If the end of the input stream is reached during this operation, both <code>eofbit</code> and <code>failbit</code> are set, and no input takes place.
</li>
<li> The I/O manipulator <span class="t-lc"><a href="../manip/ws.html" title="cpp/io/manip/ws">std::ws</a></span>, if it reaches the end of the stream while consuming whitespace (but, unlike the formatted input sentry, it does not set <code>failbit</code> in this case)
</li>
<li> The unformatted input functions <a href="../basic_istream/read.html" title="cpp/io/basic istream/read"><tt>basic_istream::read</tt></a>, <a href="../basic_istream/get.html" title="cpp/io/basic istream/get"><tt>basic_istream::get</tt></a>, <a href="../basic_istream/peek.html" title="cpp/io/basic istream/peek"><tt>basic_istream::peek</tt></a>, and <a href="../basic_istream/getline.html" title="cpp/io/basic istream/getline"><tt>basic_istream::getline</tt></a>, when reaching the end of the stream.
</li>
<li> The discard input function <a href="../basic_istream/ignore.html" title="cpp/io/basic istream/ignore"><tt>basic_istream::ignore</tt></a>, when reaching the end of the stream before reaching the specified delimiter character.
</li>
<li> The immediate input function <a href="../basic_istream/readsome.html" title="cpp/io/basic istream/readsome"><tt>basic_istream::readsome</tt></a>, if <a href="../basic_streambuf/in_avail.html" title="cpp/io/basic streambuf/in avail"><tt>basic_streambuf::in_avail</tt></a> returns <span class="t-c"><span class="mw-geshi cpp source-cpp"><span class="sy2">-</span><span class="nu0">1</span></span></span>
